March 6, 2005 World-class racing on machinery closely related to that on the showroom floor is what continues to drive the success of the World Superbike and Supersport Championships. With four races now complete in the World Superbike Championship, it now seems certain that Honda, Ducati, Yamaha and Suzuki all have realistic chances of taking the title, with as many as ten potential race-winning riders on the grid. Realistically though, championship leader TroyBayliss (Ducati 999, 75 pts), James Toseland (Honda CBR1000RR, 74 pts), Troy Corser (Suzuki GSXR1000, 63 pts), MotoGP veteran Alex Barros (Honda CBR1000RR, 55 pts) and Noriyuki Haga (Yamaha YZF R1, 42 pts) will be the key players with both Barros and Haga set for significant machinery improvements in the coming weeks. In the Supersport championship, the title already looks to be a race between the Ten Kate Honda CBR600RR of reigning champ Sebastien Charpentier and the Yamaha Germany YZF-R6 of Kevin Curtain.
